Purpose To compare two calculators for toric intraocular lens (IOL) calculation and to evaluate the prediction of refractive outcome. Methods Sixty-four eyes of forty-five patients underwent cataract surgery followed by implantation of a toric intraocular lens (Zeiss Torbi 709 M) calculated by a standard industry calculator using front keratometry values. Prediction error, median absolute err...

optical rehabilitation of the patient with aphakia who cannot tolerate contact lenses present a therapeutic challenge. in the absence of capsular support, anterior chamber lenses have been widely used. on the other hand intraocular lens implantation of scleral sutured posterior chamber intraocular lens during penterating keratoplasty or insufficient iris support is recommended. the purpose of t...

This article compares methods of axial length measurement for determining intraocular lens power and describes bimanual micro incision phacoemulsification for refractive lens exchange and routine cataract surgery, which offers an enormous advantage of maintaining a more stable intraocular environment during lens removal. This advantage may be especially important in high myopes who are at a gre...

purpose : to report clinical and pathological features of three cases of opacification with hydrophilic acrylic intraocular lenses (iols) case reports : in this interventional case report, we introduce the surgical and laboratory information about three hydrophilic acrylic iols which calcified after implantation for these patients with cataract. these lenses were explanted and analyzed with opt...

PURPOSE The purpose of this study was to evaluate the effect of pupillary dilation on the Haigis formula-calculated intraocular lens (IOL) power and ocular biometry measurements by using IOLMaster(®). METHODS A prospective study was performed for biometry measurements of 373 eyes of 192 healthy subjects using the IOLMaster at the outpatient department of King Chulalongkorn Memorial Hospital f...

Purpose. To assess the repeatability and reproducibility of ocular biometry and intraocular lens (IOL) power measurements obtained by ophthalmology residents using an AL-Scan device, a novel optical biometer. Methods. Two ophthalmology residents were instructed regarding the AL-Scan device. Both performed ocular biometry and IOL power measurements using AL-Scan, three times on each of 128 eyes,...
